Hello,
I am attempting to create new records based on when an email arrives in a shared inbox. I have the flow creating a new record with all the required data and and have attempted a loop in the event that multiple files are attached. I have gotten it to upload a file successfully, but it was just a .txt file containing the metadata. Step #8 finds the record based on the ID used in step #5.
